  • Leaks are also on this list and would represent the cheapest repair depending on how low the oil level got in the differential.
  • The vibrations will get even worse if there is a differential fluid leak.
  • For example, the source of a humming noise can be linked to other issues, such as tires and the CV joint.

The rear differential ensures proper control of your vehicle and allows the driver to drive in the direction he wants. Rear differential repair and replacement costs can vary substantially, however a general guideline can be followed.

Open Differential

Even buying a high-quality used component that still has a solid warranty will cost between $1,500 and $2,000 once you have it installed. If you prefer a new rear differential, expect to pay closer to $3,000 to $4,000. It is wise to get a new rear differential instead of a used one since this will give you more confidence in the part and it should last longer. One of the most important ways to extend the lifespan of your differential is to change the differential fluid regularly. This fluid is more viscous than the motor oil, so you need to change it when it reaches between 30,000 to 50,000 miles.

  • Diff noise tends to be more of a whine or a whistle, and tire noise is more of a white noise or hum.
  • It could be a symptom of a rear-end differential or a sign of other automotive issues from the rear wheels.
  • Light brown or grayish fluid on the ground under the back of your truck is an indication that you have a differential fluid leak.
  • Perhaps the differentials are leaking fluid and that is causing them to wear prematurely.
  • Just as its name suggests, a limited-slip differential limits how much a wheel can spin by transferring power to a tire with more traction.

As a result, it can take up to five hours to finish this task, which means it’s more expensive to do so. Because of this, if one tire loses traction while the other retains it, the power can be limited. The parts department at the dealer will be able to look up the correct fluid for the transfer case by your VIN.

Disabled Differentials

The basic idea is that when a tire slips, the maximum wheel speed of a slipping tire is limited. Torque is then transferred or multiplied to the opposite tire that still has grip. Ideally, this allows a vehicle to keep moving forward even if one tire has little or no grip. A differential is the part of a vehicle’s powertrain that allows two wheels to turn at different speeds. Differentials have one input and two outputs, with each output going to an axle or drive shaft which then connects to a wheel.

  • Both these scenarios can potentially make you loose control of the car depending on the speed you are traveling at and road conditions.
  • Multiple broken teeth will likely cause thunks and rattling sounds.
  • If you replace the driveshaft, you must ensure that the balance is correct.

5 Symptoms of a Bad Front or Rear Differential and Repair Cost

The cost to repair a bad rear differential can range anywhere from $200-$2000, depending on the severity of the damage and whether or not replacement parts are needed.
